the recommended pressure by all tyre shops is 32

I disagree mate sorry! :) AAMI and myself recommend 36psi... i use 36psi and AAMI (when i went on an advanced driving course(3 days ago) recomedned 36psi for my car) the only skyline there on the day...It was awesome :)

36 sounds a bit much, but it depends on the tyre.

I was taught to run 2psi higher in the front. It holds the tyre firmer, and reduces understeer.

Silver-Arrowz, you really should be RAISING the tyre pressure for the track, but check the pressures HOT. Anything up to around 45psi. Just depends on how the car feels, and what tyres are fitted.

It's not a simple case of raising or lowering the pressures for the track. You have to find a happy medium which will allow the tyres to bleed off excess temperature. Either too high or too low pressure will cause them to overheat. Usually low to mid 30's for pressure is good but you really have to experiment.

I run mine on about 36 for the street, used to run up to 40 on my previous car but found the sidewalls got slightly distended after awhile. I haven't taken the car to the track yet so I don't know which way to move it from here, I'll have to experiment myself.

I use to run 38psi in my Falkens. I've since had a set of RE540's fitted & was recommended to run ~30-32psi (cold) for the road. These tyres have VERY stiff sidewalls.

When it come to road use it really depends on what your driving style is?

Traffic light specialists would probably benefit from lower pressures (~28-30psi cold) as the extra sidewall flex "should" help with grip. Plus the ride will be a tad more comfortable.

If you're more of a twisty road person then extra pressure "should" be better (36+psi cold).

I'm no expert on this stuff so I could be completely wrong!? And you'll end up with lots of - :burnout:

I found 37psi (cold) was good but I have run 45 psi (cold) and found it a bit to harsh, my tyres are stamped 55 psi max.

What I have noticed is the firmer the suspension the more the sidewall flex becomes an issue.

If you are worried about the presure getting to hight when the tyres are warm then fill them with nitrogen, only problem I have is to top them up I need to go to the tyre shop.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
